Robin Hadlock Seeley, a Cornell marine biologist, spearheaded an invasive species survey of Cobscook Bay, Maine, that has discovered a sea squirt there that could potentially threaten the important fishing area.
If Cornell University researchers and their colleagues have their way, cheetahs, lions, elephants, camels and other large wild animals may soon roam parts of North America. (Aug. 17, 2005)
Cornell scientists have developed a rapid, less costly and sensitive new technique for detecting group A streptococcus, the bacteria that cause scarlet fever. Details will be announced July 18 at the Institute of Food Technologists Annual Meeting and Food Expo in New Orleans.
A new Cornell study finds that it is primarily people whose ancestors came from places where dairy herds could be raised safely and economically, such as in Europe, who have developed the ability to digest milk. (June 1, 2005)
Move over, quantum dots. Make way for the new kids on the block -- brightly glowing nanoparticles dubbed "Cornell dots." By surrounding fluorescent dyes with a protective silica shell, researchers have created fluorescent nanoparticles with possible applications in displays, biological imaging, optical computing, sensors and microarrays such as DNA chips.

Some people are never satisfied. First, nanotechnology researchers at Cornell built a device so sensitive it could detect the mass of a single bacterium - about 665 femtograms. Then they built one that could sense the presence of a single virus - about 1.5 femtograms. Now, with a refined technique, they have detected a single DNA molecule, weighing in at 995,000 Daltons - a shade more than 1 attogram - and can even count the number of DNA molecules attached to a single receptor by noting the difference in mass.

U.S. President George Bush, Vice President Dick Cheney and Secretary of Defense Donald Rumsfeld may not all get a library, airport or highway named after them. But each has a slime-mold beetle named in his honor.
Although most people think of bats as stealthy mammals that flit about in the night sky, at least one species has evolved a terrestrial trot never before seen in bats, according to a recent study.
